WASHING MACHINE.

Application filed, June 20,

My invention relates to washing machines. One of the principal objects of my invention is to provide an improved washing ma- .chinefwhichwill imparta movement to the clothes and water which will result in a thoroughcleansing ofeevery part of each piece of clothing contained therein without injury. '1 I a A further object of my invention is to provide an improved power-driven washing machine provided with means for disconnecting the oscillatable tub from the driving mechanism and bringing the oscillatable tub'to rest in a definite position. 1 A further object of my invention is to simplify the driving mechanism for the washing mechanism and wringer. A further object is to provide an improved washing machine-which will be simple in construction, durable and efficient in use, safe and easy to operate. f 7 Further objects will appear from the detailed descriptionto follow and from the appended claims. I

In the drawings in which several embodiments of my invention are shown;-

Fig. 34is a perspective viewYof the tub with parts broken away to show the interior construction; 7 f

Fig. 1 is a view corresponding to Fig. 3

' but showing a different form of oscillatable tub' a v 5 is a section on the line 9 -9 of Fig, 4.

Referring first to Figs. 1 to 3 inclusive,

the construction shown therein comprises an oscillatable tub 15, in which the clothes are placed, a wringer construction 16, an tric. motor 17 for driving the tub 15 and wringer 16, transmission mechanism 18, -between the motor 17 and the tub 15 and 1 wringer, 16, and a frame-work 19 for supporting the tub 15, wringer16, motor 17-and transmission 18. I

One of the important features ofmy invention is the provision of means whereby as the clothes are caused to move back and forth they are also caused to rotate as a mass about a substantially vertical axis, the combined motion being a sort of to and fro move- 1 ment combined with a whirlpool movement.

In the construction shown in Figs. 1 to 3 inclusive, this is elfected'by the provision of elec- 1921.. Serial No. 478,778.

a pair of projections 20 .and21 inside the tub 15, located on opposite'sidesof the tub, As shown in Fig. 4, each of these projections 21 has a gradually inclined upper face 22 ders the return movement of that part of the mass of clothes engaged by it.

' As indicated by the arrows A in Fig. 3,

the combined effect of the projections 20 and 21 is to cause a unidirectional rotation of the clothes in thetub about a vertical axis, the unidirectional rotation being combined with a reciprocating movement ofthe clothes effected by the oscillation of the tub 15. This movement of the clothes exposes all partsof the mass to the action of the water which is caused to move back and forth by the movement of the tub, and results in a thorough cleansing ofevery part of each garment.-

3 The transmission 18 for the tub 15 and j wrin'ger16' comprises a worm 24', driven directly from the motor-shaft 25, and transmission 26 between the worm 24 and the tub 1'5- .e

'The transmission 26 between the worm "24: and the tub 15 comprises a worm-gear 28 meshing with the worm 24,11. shaft 29 on which the worm-wheel 28 is mounted, a crank 31 mounted on the shaft 29, an'da connecting rod 32'pivotally connected at one end to the crank 31 and at the other end to the oscillatable tub 15.

For stabilizing the action of .theoscillatable tub 15 and preventing undue strain due tothe reversal of movement, stabilizing coil tension springs 35 may be provided, secured at one end to the frame 19 and. at the other end to the oscillatable tub.

, In Figs; 4; and 5, is shown a different form 7 of tub which can be substituted for the tub 15 shown in Fig. 1. This tub 55 'is set'at an angle to the shaft 56 on which it is oscillatably mounted, and is provided on its opposite side gated members 57 and 58, the effect of'which is to impart a whirlpool action to the clothes in addition to the to and fro movement caused by the oscillation of the tub as indi-i m5 walls with projecting corrucated by the arrows B. As the tub 55 is v rocked to move theclothes toward the end member 57, the clothesare thrown against I this corrugated member and retarded in their movement, the other. side of the mass of clothes moving forward freely. tends to cause a movement of the clothes in the direction of the arrowsv 13. Similarly when the mass of clothes is thrown toward that end of the tub provided with the corrugated 58, the clothes are thrown into engageinent ii ith' the corrugated member and that portion or the clothes in engagement withthe corrugated memberv is retarded in itsmoyeinent while the opposite side of the mass, of clothes moves forward freely. This alsotends" to cause a rotation of the mass of clothes in al direction indicated bythe arrows 13 so that the combined result of thefcorrugated members 57ml 58 is to cause a unidirectionalmoveinent of rotation of the mass of clothes about avertical an is.

Haring thus described my invention, what I claim as new and desire to's'ec ureby Letters Patent of the United States isi v 1 A washing machine comprising a tub, and means for ihfrpai-tingto the clothes in said tub a back and forth movement, and also a movement of rotationabout a sub stantially vertical aXis, said last ineans comprising two projections, one on each side of the tub, each projection being constructed to allow the clothes in contact therewithto slide past easily in on e direction, and hav ing an abrupt shoulder tohinder the moven ient of the clothes. therepast the opposite direction.
